Comparing the Effect of Eight Weeks of Aerobic and Combined Exercise on Some Hemorheological Indicators in Middle-Aged Male Patients Undergoing Coronary Artery Bypass Graft Surgery

Abstract

Background: Hemorhological disorders are one of the primary causes of cardiovascular diseases. Accordingly, aerobic and combined exercises can improve hemorhological indicators and reduce cardiovascular complications in high-risk people. Objectives: This study aimed to compare the effects of eight weeks of aerobic and combined exercise on some hemorheological indicators in middle-aged male patients undergoing Coronary Artery Bypass Graft Surgery. Methods: This experimental study was conducted in 2023 on 30 middle-aged men (Age, 57.63 ± 6.38, BMI, 26.61 ± 3.60) undergoing Coronary Artery Bypass Graft Surgery in Kermanshah, Iran, who were divided into aerobic (10 people), combined (10 people), and control (10 people) groups. The intervention groups received selected exercises for eight weeks (24 sessions). Serum hemoglobin, hematocrit, fibrinogen, and erythrocyte sedimentation rate (ESR) were measured before and after the intervention. The parametric paired sample t-test and one-way ANOVA test were used to examine differences at a significance level of P ≤ 0.05. Results: The effect of combined exercises on hemoglobin and hematocrit was significant (P ≤ 0.05), but the amount of reduction in the aerobic group was not significant (P > 0.05). Findings in the fibrinogen and ESR variables showed a significant decrease in both aerobic and combined groups (P ≤ 0.05). There was no significant difference between the effect of eight weeks of aerobic and combined training on the variables of hemoglobin, hematocrit, fibrinogen, and ESR (P > 0.05). Conclusions: Based on the results, aerobic and combined exercises effectively improved the hemorheological indicators and overall conditions of patients who underwent Coronary Artery Bypass Graft Surgery. Therefore, these exercises should be included in the cardiac rehabilitation program as an effective treatment method.
